php - Symfony 4.4 - 添加具有多对多关系的数据库的问题
问题描述
我对多对多关系有一点问题。我有一个用户类和一个技能类(能力),我将它与多对多关系联系起来,这样我就得到了技能用户(能力用户)表。问题是我无法通过表单将数据添加到此表中。谢谢您的帮助。
ps:我有这个错误:
属性“competences”和方法之一“getCompetences()”、“competences()”、“isCompetences()”、“hasCompetences()”、“__get()”都不存在并且在类“App\”中具有公共访问权限实体\能力”。
能力等级:

表格 :
<?php
namespace App\Form;
use App\Entity\Competence;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\OptionsResolver\OptionsResolver;
class UserCompetenceType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('competences')
->add('apprenant')
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Competence::class,
]);
}
}
解决方案
更具体地说,假设您有实体User
,并且在您的User
实体内部,您有不同的属性,例如title, description
您命名它。因此,builder->add
您只能指定User
实体的属性:
builder->add('title')
builder->add('description')
